IMPROVED ELECTRICAL AMALGAMA'I'OR. W The Schedule referred to in these Letters Patent and making part of the same. o-4 p.

Be it known that I, J U'LIO H. RAE, of Syracuse, in the county of Onondaga, and State of New York, have invented a new and useful Improvement in Electrical Amalgamators; and I do hereby declare the following to be a full, clear, andexact description'thereof, which will enable those skilled in the art to make and use drawing-forming partofthis specification, in which Figure 1 represents a longitudinal central section of this invention. A

' Figure 2 is atransverse section thereof. I Similar letters indicate corresponding parts.

This invention relates to an apparatus which I use in carrying out a process for treating auriferous and me, February 5, 1867, and which consists. in exposing such ores to the combined action of a current of electricity, and of suitable solvents or chemicals, for the purpose of separating from said ores the gold, silver, or other metals contained therein.

The apparatus, which forms the subject-matter of my present invention, consists ina cylindrical drum,

two heads, to the inner sides of which is secured a mercury, and a solution of salt, or any othm' suitable excitingeliquid, and by revolving the drum, a galvanic" current is produced, which efiectually assists in separat-, ing the gold, silver, or other metal from the ganguek- A represents a drum, made of sheet-iron, or any other suitable material, and provided with-a lining, B, of corrugated sheet-copper. Said drum is provided attached a heater, D, which is made of zinc, in any desirable form or shape. The connection between the heater and the heads is protected by India rubber, or otherinsulating-material, so that the heater is insulated from the body of the drum.

From the outer surface of the heads project the gudgeons a, which have their bearings in suitablestandards, so that a revolving motion can be imparted to the drum by hand or other suitable power.

A door or man-hole in the circumference, or in one of the heads of the drum, gives access to the interior thereof, and serves to introduce or remove the pulverized ore, and the agents used in the process.

In using this apparatus, I introduce a quantity of pulverized ore, an equivalent quantity of mercury,

and a quantity of salt water, or other agent capable of excitin a galvanic current when brought in conetact with t 1e proper elements. I then close the drum,

and, by revolving the same, the pulverized ore is.intimatelymixedwith the'rnercnry,'and at the same I time a galvanic current is created by the action of the salt-water or other agent on the copper lining and zinc heater, and by the action of this. current, the separation of the gold,' silver, or other metal contained in'the ore, from the gangue, is materially'iacilitated, as firlly described in my Letters Patent'of February 5, 186". It is obvious that the lining may be made of zinc and the beater of coppenor any other suitable materials may be selected for the two elements of. my

galvanic battery, without changing the principle of my invention. p Having thus described my invention,

What I claim as new, and desire to secure byLetters;

Patent, is- I The drum A, provided with a lining and with a heater, representing the two elements of a galvanic battery, said beater serving also to bring all the par: ticles of the pulverized gore'in intimate contact with the mercury, substantially as herein shown-and described. V
